The amendments provide for an extension of the term of the loan facility from December 31, 2002 to December 31, 2005, which is further extended to December 31, 2010 if a production decision on the Midwest project has been taken prior to the end of 2005. At the expiry of the term, the loan balance must be reduced by 20% per year and interest payments made monthly. As part of this agreement, Denison has the right to prepay any amount and redraw on 45 days' notice all such prepayments together with the interest, at bank prime plus 1%, not incurred as a result of all such prepayments. Denison prepaid $12 million in November 2000 as part of interim arrangements pending completion of the detailed amendments and thereby reduced the Company's interest costs while at the same time maintaining its access to these funds as it may require. The loan balance will be approximately $53 million on January 31, 2001 after applying receipts from all fourth quarter uranium sales. Denison is also pleased to announce that it has executed an agreement for Denison Environmental Services to perform all the services for the five closed mine sites of Rio Algom in Elliot Lake, Ontario. The agreement has an initial term of five years and includes all monitoring, effluent treatment, maintenance, data storage and reporting activities associated with the five closed mine sites. In Saskatchewan, the first oil well drilled in which Denison has earned a 50% interest is producing at 5 - 20 barrels of oil per day from a vertical section. Consideration of completing a horizontal leg into the producing zone is underway. Drilling of an exploration well in another prospect is commencing today. -30- FOR FURTHER INFORMATION PLEASE CONTACT: Denison Mines Limited E.
